This is one of a series of stories and videos in which TheWrap explores the background, history and repercussions of the events depicted in the film “The Post,” from the commission and leak of the top-secret Vietnam chronicle the Pentagon Papers to the legal battle over its publication.

These are landmark moments in the history of the Washington Post, the newspaper that gives title to and serves as the setting for “The Post”:

1877 The Washington Post is founded by Stilson Hutchins.

1880 The Post adds a Sunday edition to become the city’s first newspaper to publish seven days a week.

1889 The paper is taken over by new owners: Frank Hatton, a former postmaster general, and Beriah Wilkins, a former Democratic congressman from Ohio.

1894 – 1905 After several changes at the top, John Roll McLean, the owner of the Cincinnati Enquirer, becomes the Post’s new owner.

1972 The Post’s coverage of a break-in at the Watergate hotel complex grows into a sprawling investigation of Nixon administration misconduct led by young reporters Bob Woodward and Carl Bernstein. The reporting wins the Post a Pulitzer for Public Service and results in the 1974 resignation of President Richard Nixon.

1976 “All the President’s Men,” a film based on the book by Woodward and Bernstein, is released and receives eight Oscar nominations, including Best Picture.
